Splice is much more efficient, and the only reason it isn't working here is you're skipping the item after each item you remove. The following works fine:
my @c = (1..20);
for ($i = 0; $i <= $#c; $i++) {
if ($c[$i] >= 5 && $c[$i] <= 10) {
splice(@c,$i,1); $i--;
}
}
print join ' ', @c;
Outputs:
1 2 3 4 11 12 13 14 15 16 17 18 19 20
Or for your example:
my @c = ("bob", "bob", "martha", "bob");
for (my $i = 0; $i <= $#c; $i++) {
if ($c[$i] eq "bob") {
splice(@c,$i,1); $i--;
}
}
print join ' ', @c;
